Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTLW-102-07-F-S-280 is determined by the following critical parameters:

• Connector Type: Header (standard or breakaway variants acceptable)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 2 — exact match required
• Number of Rows: 1 — exact match required
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant or equivalent

The 3M 929450-01-02-I meets these core substitution criteria. Both parts share identical pitch, position count, row configuration, mounting method, and termination type. Both feature gold-plated mating contacts, UL94 V-0 flammability ratings, and RoHS compliance. Variations in contact length, insulation height, current rating, and operating temperature range are secondary parameters that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MTLW-102-07-F-S-280 and 929450-01-02-I are active production parts with UL94 V-0 flammability certification and RoHS compliance. Selection between these parts depends on application-specific requirements not addressed by substitution criteria alone.

The MTLW-102-07-F-S-280 operates across a wider temperature range (-55°C to 125°C) and supports higher current per contact (5.2A). The Samtec part features Liquid Crystal Polymer insulation and Phosphor Bronze contacts with thinner gold plating.

The 929450-01-02-I operates within -40°C to 105°C and supports 2.5A per contact. The 3M part features PBT insulation with glass reinforcement and Copper Alloy contacts with thicker gold plating (10.0µin). The 3M connector includes breakaway functionality and exhibits greater overall contact length and insulation height.

Both parts share identical pitch, position count, and mounting configuration. Substitution is mechanically and electrically feasible where application current and temperature requirements fall within the 929450-01-02-I specifications.

Frequently Asked Questions (FAQ)

Q: Can the 929450-01-02-I replace the MTLW-102-07-F-S-280 in all applications?

A: Substitution is valid only when application requirements satisfy the 929450-01-02-I specifications. The 3M part supports maximum 2.5A per contact and operates to 105°C maximum. If the application requires 5.2A per contact or operation above 105°C, the MTLW-102-07-F-S-280 is required.

Q: What are the physical differences between these connectors?

A: The 929450-01-02-I has greater overall contact length (0.535" vs 0.430"), higher insulation height (0.110" vs 0.060"), and longer post length (0.130" vs 0.090"). The 3M part includes breakaway functionality. These dimensional differences may affect PCB layout and mating depth.

Q: Are both parts RoHS compliant?

A: The MTLW-102-07-F-S-280 is ROHS3 Compliant. The 929450-01-02-I is REACH Unaffected. Both meet environmental compliance standards applicable to their respective markets.

Q: What is the difference in gold plating thickness?

A: The MTLW-102-07-F-S-280 features 3.00µin (0.076µm) gold plating on mating contacts. The 929450-01-02-I features 10.0µin (0.25µm) gold plating. Thicker plating on the 3M part provides enhanced wear resistance in high-cycle mating applications.

Q: Can these connectors be used interchangeably on the same PCB?

A: Mechanical interchangeability is not guaranteed due to dimensional differences in contact length, insulation height, and post length. PCB footprint and mating depth must be evaluated for each part before substitution.
