Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-282825-8 is determined by the following critical parameters that must align across equivalent parts:

Primary Substitution Criteria:

• Number of positions: 18 (fixed requirement)
• Termination style: Solder (fixed requirement)
• Mounting type: Through hole (fixed requirement)
• Header orientation: Vertical (fixed requirement)
• Voltage rating: Minimum 300V UL
• Current rating: Minimum 15A UL
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Pitch tolerance: 0.200" (5.08mm) nominal with 0.197" (5.00mm) acceptable within mechanical envelope constraints
• Contact tail length and insulation height must accommodate existing PCB footprints
• Shrouding configuration (2-side vs. 4-side) affects mechanical fit but does not preclude substitution if mounting geometry is verified

The substitute parts identified (Phoenix Contact 1755668 and Assmann WSW Components A-TB500-OQ18CV) meet the core electrical and mechanical requirements while offering active product status and enhanced current ratings.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755668 (COMBICON MSTBVA Series)

The Phoenix Contact 1755668 is an active product offering equivalent electrical performance with 12A UL current rating and 300V UL voltage rating. This part meets all core substitution criteria including 18-position configuration, vertical through-hole mounting, solder termination, and UL94 V-0 flammability compliance. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. The 4-side shrouding provides enhanced mechanical protection compared to the 2-side shrouding of the original part. Contact tail length of 0.154" (3.90mm) differs from the original 0.138" (3.50mm), requiring PCB footprint verification. This part is suitable for applications where the 12A current rating satisfies design requirements.

Assmann WSW Components A-TB500-OQ18CV

The Assmann WSW Components A-TB500-OQ18CV is an active product offering enhanced electrical performance with 20A UL current rating and 300V UL voltage rating. This part meets all core substitution criteria including 18-position configuration, vertical through-hole mounting, solder termination, and UL94 V-0 flammability compliance. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. The 4-side shrouding provides enhanced mechanical protection. Contact tail length of 0.138" (3.50mm) matches the original part, facilitating direct PCB footprint compatibility. Operating temperature range of -40°C to 115°C exceeds the original specification. This part is suitable for applications requiring higher current capacity or extended temperature performance.

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the original 1-282825-8 component.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755668 or Assmann WSW Components A-TB500-OQ18CV be used as direct replacements for the TE Connectivity 1-282825-8?

A: Both parts satisfy the core electrical and mechanical requirements: 18-position configuration, vertical through-hole solder termination, 300V UL rating, and UL94 V-0 compliance. However, pitch tolerance (0.197" vs. 0.200") and contact tail length variations require PCB footprint verification before implementation. The Assmann part offers identical contact tail length (0.138"), while the Phoenix Contact part has a longer tail (0.154").

Q: What is the significance of the pitch difference between 0.200" (5.08mm) and 0.197" (5.00mm)?

A: The pitch difference of 0.003" (0.08mm) is within typical manufacturing tolerances for terminal block headers. However, cumulative tolerance across 18 positions may result in measurable spacing variations. PCB hole pattern verification is required to confirm mechanical compatibility before substitution.

Q: How do the current ratings of the substitute parts compare to the original?

A: The original 1-282825-8 is rated at 15A UL. The Phoenix Contact 1755668 is rated at 12A UL, which is below the original specification. The Assmann WSW Components A-TB500-OQ18CV is rated at 20A UL, which exceeds the original specification. Application current requirements determine which substitute is appropriate.

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

A: The original 1-282825-8 features 2-side shrouding, while both substitute parts feature 4-side shrouding. Four-side shrouding provides enhanced mechanical protection and isolation. This configuration difference does not affect electrical performance but may impact mechanical fit in constrained mounting environments.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the Phoenix Contact 1755668 and Assmann WSW Components A-TB500-OQ18CV are ROHS3 compliant. The Phoenix Contact part has REACH unaffected status, and the Assmann part also has REACH unaffected status, confirming regulatory compliance for both substitutes.

Q: What is the contact tail length significance?

A: Contact tail length determines the solder joint depth on the PCB. The original part has a 0.138" (3.50mm) tail. The Assmann part matches this specification, while the Phoenix Contact part has a 0.154" (3.90mm) tail. Longer tails may require PCB hole depth adjustment or create solder joint geometry variations.

Q: Can I use the substitute parts in applications requiring the full 15A rating?

A: The Phoenix Contact 1755668 is rated at 12A UL, which is insufficient for applications requiring 15A. The Assmann WSW Components A-TB500-OQ18CV is rated at 20A UL and is suitable for applications requiring up to 15A operation.
