Substitute Part Grouping Explanation

Substitution eligibility for the 85674-145 is determined by the following critical parameters:

Connector Position Count: 30 positions (fixed requirement)
Pitch Specification: 0.079" (2.00mm) (fixed requirement)
Row Configuration: 5 rows (fixed requirement)
Connector Type: Header with male pins (fixed requirement)
Mounting Method: Through-hole press-fit termination (fixed requirement)
Contact Finish: Gold plating at 30.0µin minimum (fixed requirement)
Current Rating: Minimum 1A (equal or greater acceptable)
Operating Temperature: -55°C ~ 125°C (equal or greater range acceptable)
Flammability Rating: UL94 V-0 (equal or greater acceptable)

Two substitute parts meet these criteria:

85674-145LF (Amphenol ICC): Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs only in product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

MP2-H030-51P1-S-KR (3M): Functionally equivalent 30-position header with identical pitch, row count, and mounting method. Provides enhanced current rating (1.5A vs. 1A) and includes board guide and mating guide features. Operates within the same temperature range with equivalent flammability rating.

Engineering Selection Recommendations

85674-145LF is the primary substitute for direct replacement applications. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The transition from the obsolete 85674-145 to the 85674-145LF presents no functional or dimensional compatibility issues.

MP2-H030-51P1-S-KR serves as a functional alternative where enhanced current capacity and integrated mechanical features provide system benefits. The 1.5A current rating exceeds the 1A requirement of the original part. The inclusion of board guide and mating guide features improves connector alignment and mechanical stability during mating operations. This part is suitable for new designs and retrofit applications where the additional features do not conflict with existing mechanical constraints.

Both substitutes maintain compliance with UL94 V-0 flammability requirements and operate across the full -55°C to 125°C temperature range specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can 85674-145LF be used as a direct replacement for 85674-145?

A: Yes. The 85674-145LF is a direct equivalent with identical position count (30), pitch (2.00mm), row configuration (5), connector type (header male pins), mounting method (through-hole press-fit), contact finish (gold 30.0µin), and current rating (1A). The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant).

Q: What are the mechanical compatibility considerations for MP2-H030-51P1-S-KR?

A: The MP2-H030-51P1-S-KR maintains the same 30-position, 2.00mm pitch, 5-row configuration as the original part. The addition of board guide and mating guide features does not affect PCB footprint compatibility. Verify that the connector's beige color and Futurebus+® style designation do not conflict with existing mechanical or aesthetic requirements.

Q: Does the higher current rating of MP2-H030-51P1-S-KR affect compatibility?

A: No. The 1.5A rating of the MP2-H030-51P1-S-KR exceeds the 1A requirement of the original part. Higher current capacity does not create compatibility issues and provides additional design margin for applications approaching the original current limit.

Q: Are there packaging differences between these substitutes?

A: The 85674-145 packaging is not specified. Both 85674-145LF and MP2-H030-51P1-S-KR are supplied in tube packaging. Verify tube quantity and handling requirements align with procurement and assembly processes.

Q: What compliance certifications apply to each part?

A: All three parts carry UL94 V-0 flammability ratings and operate across -55°C to 125°C. The 85674-145 is RoHS non-compliant. Both 85674-145LF and MP2-H030-51P1-S-KR are RoHS compliant. For applications requiring RoHS compliance, use 85674-145LF or MP2-H030-51P1-S-KR.
