Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901200928 is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — all substitutes must match this spacing
Number of Positions: 8 positions — all substitutes must maintain this configuration
Contact Type: Male Pin — all substitutes must use male pin contacts
Mounting Type: Through Hole — all substitutes must support through-hole PCB mounting
Termination: Solder — all substitutes must use solder termination
Connector Type: Header configuration — all substitutes must be header-style connectors
Material Flammability Rating: UL94 V-0 — all substitutes must meet this safety standard

All substitute parts listed below satisfy these core electrical and mechanical parameters. Variations in contact length, insulation height, contact finish thickness, and operating temperature ranges are secondary parameters that do not prevent functional substitution in standard applications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS3 or equivalent RoHS standards. The following considerations apply to part selection:

Primary Substitutes (Highest Compatibility)

The Amphenol ICC 77311-124-08LF, TE Connectivity 826629-8, and Harwin M20-9990846 are direct functional equivalents. These parts share the same 8-position, 2.54mm pitch configuration with gold-plated mating contacts and tin-plated posts. All three maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels.

Temperature Range Considerations

The Molex 0901200928 operates from -55°C to 125°C. The Amphenol ICC 77311-124-08LF matches this upper temperature limit at 125°C. The TE Connectivity 826629-8, Harwin M20 series parts, and Hirose A2-8PA-2.54DSA(71) operate at reduced maximum temperatures (85°C to 105°C). Selection should account for application thermal requirements.

Contact Finish Variations

Gold-finished mating contacts are present in the Molex original, Amphenol ICC, TE Connectivity, Hirose, and Harwin M20-9990845/9730845 variants. The Harwin M20-9990846 and M20-9730846 use tin-finished mating contacts. Contact finish selection depends on application corrosion resistance and connector mating cycle requirements.

Insulation Material Differences

The Molex original uses polyester with glass filling. Substitutes employ polybutylene terephthalate (PBT), thermoplastic, or polyamide (PA6T/Nylon 6T) insulation. These materials are functionally equivalent for standard through-hole applications and maintain equivalent flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0901200928 with any of the listed parts?

A: Yes. All listed parts share the critical parameters: 8 positions, 0.100" (2.54mm) pitch, male pin contacts, through-hole mounting, solder termination, and UL94 V-0 flammability rating. These parameters define functional compatibility for standard board-to-board and cable connection applications.

Q: What is the difference between gold and tin contact finishes?

A: Gold-plated mating contacts provide superior corrosion resistance and lower contact resistance over extended mating cycles. Tin-plated contacts are suitable for applications with limited mating cycles and lower corrosion exposure. Both finishes are compatible with standard solder termination.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a secondary parameter. The Molex 0901200928 operates to 125°C maximum. If your application requires operation above 105°C, the Amphenol ICC 77311-124-08LF is the only substitute that matches this specification. For applications below 105°C, all substitutes are suitable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes comply with RoHS3 or equivalent RoHS standards. The Molex original is ROHS3 Compliant. All substitutes carry either ROHS3 Compliant or RoHS Compliant designations.

Q: What is the significance of the "Cuttable" connector type in Harwin parts?

A: The Harwin M20 series connectors feature a cuttable design, allowing individual positions to be separated from the header strip. This feature does not affect functional compatibility with standard applications but provides design flexibility for custom configurations.

Q: Can I mix contact finishes in a single application?

A: Contact finish selection should be consistent within a mating pair. If the Molex 0901200928 (gold mating finish) is used as the header, the corresponding socket connector should also feature gold-plated contacts for optimal contact resistance and reliability.

Q: What inventory levels should I consider for supply chain planning?

A: The Molex 0901200928 has 815 units in stock. Substitute parts with higher inventory include TE Connectivity 826629-8 (6484 units), Harwin M20-9990846 (7698 units), and Harwin M20-9990845 (6186 units). Higher inventory levels provide supply chain flexibility for extended production runs.
