Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance)

The Molex C-Grid 71764 series (0717640030, 0717640130, 0717640230) and Amphenol ICC BERGSTIK® series (77317-112-30LF, 77317-412-30LF, 77317-812-30LF) are active products with ROHS3 compliance and identical core mating parameters. These parts are direct functional equivalents for new designs and production transitions.

Secondary Substitutes (Active Status, Compliance Considerations)

The Amphenol ICC BERGSTIK® II series (68021-130) is active and meets core electrical parameters with extended operating temperature range (-65°C ~ 125°C). However, REACH Affected status requires verification for applications subject to REACH regulations.

The Preci-Dip 802-10-030-20-001101 is active with ROHS3 compliance and identical current rating. Operating temperature range (-55°C ~ 125°C) exceeds the original specification.

Conditional Substitutes (Compliance Limitations)

The Amphenol ICC BERGSTIK® II variant 68021-130H is active but RoHS non-compliant. This part is suitable only for applications where RoHS compliance is not required.

The 3M 961230-5804-AR is active with RoHS compliance but features a reduced current rating of 2A per contact compared to the 3A specification of the original part. This limitation restricts its use to applications with lower current requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different contact finish?

A: Yes. Contact finish variations (tin, gold, or gold with GXT™) do not affect mating compatibility or core electrical function. Selection should be based on application requirements for corrosion resistance and contact reliability.

Q: Are all listed substitutes mechanically compatible with the original M20-9701546?

A: All listed substitutes share identical pitch (0.100" / 2.54mm), position count (30), row configuration (2 rows), and mounting type (through-hole, right-angle). Mechanical compatibility is confirmed. Minor variations in contact length and insulation height do not affect board-level integration.

Q: Which substitute offers the best RoHS compliance?

A: The Molex C-Grid 71764 series (0717640030, 0717640130, 0717640230), Amphenol ICC BERGSTIK® series (77317-112-30LF, 77317-412-30LF, 77317-812-30LF), Preci-Dip 802-10-030-20-001101, and 3M 961230-5804-AR all carry RoHS3 Compliant or RoHS Compliant status. The Amphenol ICC BERGSTIK® II variant 68021-130H is RoHS non-compliant.

Q: What is the difference between the Molex variants 0717640030, 0717640130, and 0717640230?

A: All three are mechanically and electrically identical. The primary difference is contact finish: 0717640030 features tin finish, while 0717640130 and 0717640230 feature gold finish with varying thickness (15.0µin and 30.0µin respectively).

Q: Can I substitute the 3M 961230-5804-AR for the M20-9701546?

A: The 3M part meets all core mating parameters but carries a reduced current rating of 2A per contact versus the original 3A specification. Substitution is valid only if your application current requirements do not exceed 2A per contact.

Q: What packaging formats are available for these substitutes?

A: Molex parts are supplied in tube packaging. Amphenol ICC BERGSTIK® series parts are supplied in bag packaging. Preci-Dip 802-10-030-20-001101 is supplied in bulk. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there temperature range differences I should consider?

A: The original M20-9701546 operates from -40°C to 105°C. Most substitutes support extended ranges: Amphenol ICC BERGSTIK® series (-65°C ~ 130°C), Preci-Dip 802-10-030-20-001101 (-55°C ~ 125°C), and Amphenol ICC BERGSTIK® II (-65°C ~ 125°C). The 3M 961230-5804-AR operates from -25°C to 105°C. Extended temperature capability does not restrict substitution for applications within the original specification range.
