Molex 0901200792 Equivalent & Substitute Parts

Part Overview

The Molex 0901200792 is an active rectangular connector header designed for through-hole mounting applications. This 32-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part is manufactured in a breakaway configuration with unshrouded design, suitable for board-to-board or cable interconnections. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design compatibility across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901200792 is determined by the following critical parameters:

Primary Matching Criteria:

• 32-position, single-row configuration
• 0.100" (2.54mm) mating pitch
• Through-hole solder termination
• Male pin contact type
• Unshrouded design
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance
• Active product status

Secondary Compatibility Factors:

• Contact finish materials (gold mating surface preferred for signal integrity)
• Insulation material composition
• Overall contact length and insulation height (mechanical fit considerations)
• Flammability rating (UL94 V-0 preferred)

The substitute parts listed below meet the primary matching criteria and maintain functional equivalence for standard board-to-board interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original Molex 0901200792 specification.

Preci-Dip 890-18-032-10-002101 provides the closest electrical and mechanical match, with identical operating temperature range (-55°C to 125°C), gold mating contact finish, and tin post finish. This part is recommended as the primary substitute for direct replacement applications.

Harwin M20-9993245 offers functional equivalence with gold mating contacts and cuttable header design. The operating temperature range is reduced to -40°C to 105°C, which may limit use in extreme cold environments. This part is suitable for applications operating within the -40°C to 105°C window.

Samtec BBS-132-G-A and BBS-132-T-A feature circular contact geometry and nickel post finish, differing from the square contact shape of the original part. These parts maintain the full -55°C to 125°C operating range and are suitable for applications where contact geometry variation is acceptable.

Harwin D01-9923246 is classified as a SIP/SIL header with tin contact finish. Operating temperature range is not specified in available documentation. This part is suitable for general-purpose applications where temperature specifications are not critical.

Frequently Asked Questions (FAQ)

Q: Can I use Samtec BBS-132-G-A or BBS-132-T-A as direct replacements for the Molex 0901200792?

A: These parts are functionally equivalent for 32-position, 2.54mm pitch applications. However, they feature circular contact geometry compared to the square contacts of the original part. Mechanical fit in existing connector housings may differ. Verify mechanical compatibility with your specific application before substitution.

Q: What is the difference between BBS-132-G-A and BBS-132-T-A?

A: The primary difference is the mating contact finish. BBS-132-G-A features gold-plated mating contacts, while BBS-132-T-A features tin-plated mating contacts. Both maintain identical operating temperature range and nickel post finish. Gold finish is typically preferred for signal integrity and corrosion resistance.

Q: Is the Harwin M20-9993245 suitable for automotive applications?

A: The Harwin M20-9993245 operates within -40°C to 105°C, which is narrower than the original Molex part (-55°C to 125°C). For automotive applications requiring the full temperature range, the Preci-Dip 890-18-032-10-002101 is the recommended substitute.

Q: What packaging formats are available for these substitute parts?

A: Preci-Dip 890-18-032-10-002101 is supplied in bulk packaging. Samtec BBS-132-G-A and BBS-132-T-A are supplied in tube packaging. Harwin D01-9923246 and M20-9993245 are supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and maintain moisture sensitivity level 1 (unlimited), matching the original Molex 0901200792 specification.

Q: What is the difference between the Molex C-Grid III 90120 series and the substitute part series?

A: The Molex part belongs to the C-Grid III 90120 series. Substitute parts are from different manufacturer series (Preci-Dip 890, Samtec BBS, Harwin M20 and D01-99). All parts meet the same functional and electrical requirements for 32-position, 2.54mm pitch through-hole header applications.
