Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1208450000 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Substitute must have 7 positions at 0.200" (5.08mm) pitch
• Header Configuration: Substitute must be male pins, shrouded (4 side), vertical orientation
• Mounting & Termination: Substitute must support through-hole solder termination
• Electrical Ratings: Substitute must meet or exceed IEC 18A/400V and UL 15A/300V specifications
• Temperature Range: Substitute must support -50°C to 100°C operating range
• Compliance: Substitute must maintain RoHS compliance and UL94 V-0 flammability rating

The Weidmüller 1149570000 qualifies as a direct substitute based on these parameters. While it features enhanced current ratings (IEC 24A/UL 18.5A) and interlocking side features, it maintains full compatibility with the original part's core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1149570000 is the qualified substitute for the obsolete 1208450000. Selection is based on the following engineering criteria:

Product Status: The 1149570000 maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete 1208450000.

Electrical Compatibility: The substitute part exceeds the original specifications with higher current ratings (IEC 24A vs. 18A; UL 18.5A vs. 15A) while maintaining identical voltage ratings (IEC 400V, UL 300V). This provides enhanced current-carrying capacity without compromising system compatibility.

Mechanical Compatibility: Both parts share identical pitch (5.08mm), position count (7), orientation (vertical), and physical dimensions (contact tail length 3.20mm, insulation height 12.00mm), ensuring direct PCB footprint compatibility.

Compliance & Certification: Both parts maintain RoHS compliance and UL94 V-0 flammability rating, meeting regulatory requirements for equivalent applications.

Housing Material Difference: The substitute features Polyamide (PA) nylon glass-filled housing versus the original's Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 standards and support the identical operating temperature range (-50°C to 100°C).

Additional Features: The 1149570000 includes interlocking side features, providing enhanced mechanical retention without affecting electrical or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the 1149570000 be used as a direct replacement for the 1208450000 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), position count (7), contact tail length (3.20mm), and insulation height (12.00mm), ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the difference in current ratings between these parts?

A: The 1149570000 provides higher current capacity (IEC 24A vs. 18A; UL 18.5A vs. 15A) while maintaining identical voltage ratings. This enhancement does not affect compatibility with circuits designed for the original 1208450000.

Q: Are there differences in housing material, and do they affect performance?

A: The 1208450000 uses Polybutylene Terephthalate (PBT) housing, while the 1149570000 uses Polyamide (PA) nylon glass-filled housing. Both materials meet UL94 V-0 flammability standards and support the identical operating temperature range (-50°C to 100°C), ensuring equivalent thermal and electrical performance.

Q: What does the interlocking side feature on the 1149570000 provide?

A: The interlocking side feature enhances mechanical retention and positioning during assembly. This does not affect electrical performance or compatibility with the original part's electrical specifications.

Q: Why is the 1208450000 marked as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The 1149570000 serves as the active replacement, offering equivalent or enhanced specifications with continued supply availability.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1208450000 and 1149570000 are RoHS compliant and maintain UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

Q: What packaging is available for the 1149570000?

A: The 1149570000 is available in bulk packaging, with 1041 pieces in current stock.
