Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-1546575-2 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 12
• Pitch: 0.200" (5.08mm)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Termination Style: Solder
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Factors:

• Shrouding Configuration: 2-side or 4-side shrouding
• Operating Temperature Range: Minimum -40°C to maximum 105°C or higher
• Contact Mating Finish: Tin
• Housing Material: Polyamide (PA66/PA) or Polybutylene Terephthalate (PBT)
• RoHS Compliance Status: RoHS3 or RoHS Compliant
• Insulation Height: 0.472" (12.00mm) or equivalent

Substitute parts may differ in shrouding configuration (2-side versus 4-side), contact material composition (Copper Alloy versus Brass), contact tail length, and housing material formulation while maintaining functional equivalence for standard terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Shrouding Configuration):

The 1753631 (Phoenix Contact COMBICON MSTBV) provides the closest functional match with 2-side shrouding identical to the original part. This substitute maintains the same shrouding configuration while offering ROHS3 Compliance and UL94 V-0 flammability rating. The pitch specification of 0.197" (5.00mm) represents a minor deviation from the 0.200" (5.08mm) standard but remains within the same terminal block family. This part is suitable for applications where shrouding configuration is a critical design parameter.

Alternative Substitutes (Enhanced Shrouding Configuration):

The 1755833 (Phoenix Contact COMBICON MSTBVA), 0395316012 (Molex Eurostyle ESE 39531), and ELFH12250 (Amphenol PCD ELFH) provide 4-side shrouding configurations. These parts maintain the 0.200" (5.08mm) pitch, vertical orientation, through-hole mounting, and solder termination. All three are ROHS3 Compliant with UL94 V-0 flammability rating. The 4-side shrouding offers enhanced mechanical protection and EMI shielding compared to the 2-side configuration of the original part. These substitutes are appropriate when improved shrouding performance is beneficial to system design.

Compliance Verification:

All substitute parts maintain Active product status and RoHS compliance (either RoHS Compliant or ROHS3 Compliant). All parts with specified flammability ratings carry UL94 V-0 certification. Operating temperature ranges for all substitutes support the -40°C minimum requirement of the original part, with maximum ratings of 105°C or higher.

Contact Material Considerations:

The original part features Copper Alloy contacts. Substitute parts 0395316012 and ELFH12250 utilize Brass contacts. Phoenix Contact parts (1753631 and 1755833) do not specify contact material in the provided data. Brass contacts provide equivalent electrical performance and corrosion resistance for standard terminal block applications.

Mounting and Termination Compatibility:

Five of the six substitute parts (all except EDSTLZ955/12) specify through-hole mounting with solder termination, matching the original part exactly. The EDSTLZ955/12 specifies solder mounting type, which represents a different PCB integration method and should be selected only when surface-mount or alternative mounting is required.

Frequently Asked Questions (FAQ)

Q: Can the 1753631 (Phoenix Contact) be used as a direct replacement for the 1-1546575-2?

A: The 1753631 provides functional equivalence with identical 2-side shrouding configuration and through-hole solder termination. The pitch specification differs slightly (0.197" versus 0.200"), but both parts belong to the same terminal block category with 12 positions and vertical orientation. Compatibility depends on whether the 0.003" pitch tolerance is acceptable within your PCB layout specifications.

Q: What is the primary difference between 2-side and 4-side shrouding configurations?

A: 2-side shrouding (original part 1-1546575-2 and substitute 1753631) provides mechanical protection and alignment on two opposing sides. 4-side shrouding (substitutes 1755833, 0395316012, and ELFH12250) provides protection on all four sides, offering enhanced mechanical robustness and improved EMI shielding. Selection depends on application requirements for mechanical protection and electromagnetic compatibility.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry either RoHS Compliant or ROHS3 Compliant certification. The original part is RoHS Compliant. ROHS3 represents an updated compliance standard and is fully compatible with RoHS Compliant requirements.

Q: What is the significance of the contact tail length differences among substitute parts?

A: Contact tail length affects solder joint depth and PCB penetration. The original part specifies 0.055" (1.40mm), while most substitutes specify 0.130" to 0.154" (3.30mm to 3.90mm). Longer contact tails provide greater solder joint surface area and mechanical strength. Selection should verify PCB thickness and solder pad design compatibility with the specific contact tail length.

Q: Can the EDSTLZ955/12 (On Shore Technology) be used interchangeably with the original part?

A: The EDSTLZ955/12 maintains the 12-position, 0.200" (5.08mm) pitch, vertical orientation, and 4-side shrouding. However, it specifies solder mounting type rather than through-hole mounting, indicating a different PCB integration method. This part is suitable only when surface-mount or alternative mounting methods are required. Standard through-hole PCB designs should use parts with through-hole mounting specification.

Q: How do operating temperature ranges compare among the substitute parts?

A: The original part supports -40°C to 110°C. Substitute parts support -40°C to 105°C (Molex 0395316012, Amphenol ELFH12250) or -30°C to 105°C (On Shore EDSTLZ955/12). All substitutes meet the -40°C minimum requirement. If operation above 105°C is required, the original TE Connectivity part with 110°C maximum rating should be retained.

Q: What electrical specifications should be verified when selecting a substitute?

A: All substitute parts with specified electrical ratings support 300 V UL voltage rating. Current ratings vary: Molex 0395316012 and Amphenol ELFH12250 support 15 A, while Phoenix Contact parts specify 12 A. Verify that the selected substitute meets or exceeds your application's voltage and current requirements.

Q: Are there any housing material differences that affect performance?

A: The original part and most substitutes use Polyamide (PA66 or PA) nylon housing. The Amphenol ELFH12250 uses Polybutylene Terephthalate (PBT) housing. Both materials provide UL94 V-0 flammability rating and are suitable for standard terminal block applications. PBT offers slightly different mechanical and thermal properties but maintains equivalent electrical performance.
