Substitute parts are grouped into two categories based on contact material and finish specifications:

Group 1: Amphenol ICC (FCI) BERGSTIK® II Series (68695-460HLF, 68697-160HLF) These parts feature phosphor bronze contact material with tin or gold finishes. They maintain the 60-position, 2-row configuration with through-hole right-angle mounting and push-pull fastening. Operating temperature range differs from the main part.

Group 2: Amphenol ICC (FCI) BERGSTIK® Series (77317-112-60LF, 77317-412-60LF, 77317-812-60LF) These breakaway header variants use phosphor bronze contacts with gold or tin finishes. They support the same 60-position configuration and maintain compatibility with the core mechanical and electrical specifications.

Group 3: Preci-Dip 892 Series (892-18-060-20-001101, 892-18-060-20-002101, 892-70-060-20-001101, 892-70-060-20-002101, 892-80-060-20-001101) These parts use brass contact material with gold or tin finishes. They match the original part's contact length specifications and operating temperature range more closely, with identical current rating (3A per contact) and voltage rating (150VDC).

Engineering Selection Recommendations

Preci-Dip 892 Series (892-18-060-20-001101, 892-18-060-20-002101, 892-70-060-20-001101, 892-70-060-20-002101, 892-80-060-20-001101) are the primary substitutes for the M20-9953045. These parts maintain brass contact material matching the original specification, identical current rating (3A per contact), voltage rating (150VDC), and operating temperature range (-55°C ~ 125°C) that encompasses the original -40°C ~ 105°C specification. All Preci-Dip 892 variants are ROHS3 Compliant and REACH Unaffected, providing regulatory continuity.

Amphenol ICC (FCI) BERGSTIK® Series (77317-112-60LF, 77317-412-60LF, 77317-812-60LF) offer active product status with extended operating temperature range (-65°C ~ 130°C) and RoHS compliance. These parts use phosphor bronze contacts with gold or tin finishes and maintain the 3A per contact current rating. They are suitable for applications requiring extended temperature performance.

Amphenol ICC (FCI) BERGSTIK® II Series (68695-460HLF, 68697-160HLF) provide active product status with higher current rating (5A) and voltage rating (110V). These parts use phosphor bronze contacts and are appropriate for applications with increased current requirements, though operating temperature range is not specified.

Selection should prioritize Preci-Dip 892 Series for direct electrical and thermal compatibility, or Amphenol ICC BERGSTIK® Series for extended temperature performance and active product support.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC BERGSTIK® II Series (68695-460HLF, 68697-160HLF) directly replace the M20-9953045?

A: These parts maintain the critical mechanical specifications (60 positions, 2 rows, 0.100" pitch, through-hole right-angle mounting, push-pull fastening). However, they feature phosphor bronze contacts with tin or gold finishes instead of brass, and current rating is 5A versus 3A per contact. Operating temperature range is not specified for these parts. They are functionally compatible but differ in contact material and current capacity.

Q: What is the difference between the Preci-Dip 892-18, 892-70, and 892-80 series?

A: All three series maintain identical mechanical and electrical specifications (60 positions, 2 rows, 0.100" pitch, 3A per contact, 150VDC rating, -55°C ~ 125°C operating temperature). The primary differences are contact finish specifications: 892-18 uses gold mating finish with 10.0µin thickness; 892-70 uses gold mating finish with flash thickness on both mating and post; 892-80 uses tin finish on both mating and post contacts. Contact length specifications vary between 892-18/892-70 (0.236" mating, 0.118" post) and 892-18-060-20-002101/892-70-060-20-002101 (0.276" mating, 0.118" post).

Q: Are the Amphenol ICC BERGSTIK® Series (77317-112-60LF, 77317-412-60LF, 77317-812-60LF) interchangeable with each other?

A: These parts share identical mechanical specifications and are classified as breakaway headers. The primary differences are contact finish specifications: 77317-112-60LF uses gold GXT™ finish (30.0µin thickness) on mating contacts with tin post finish; 77317-412-60LF uses tin finish (78.7µin thickness) on both mating and post contacts; 77317-812-60LF uses gold GXT™ finish (15.0µin thickness) on mating contacts with tin post finish. All maintain 3A per contact current rating and -65°C ~ 130°C operating temperature range.

Q: What packaging options are available for substitute parts?

A: Preci-Dip 892 Series parts are supplied in bulk packaging. Amphenol ICC BERGSTIK® II Series (68695-460HLF) is supplied in bag packaging, while 68697-160HLF is also bag packaged. Amphenol ICC BERGSTIK® Series 77317-112-60LF is supplied in bulk packaging, while 77317-412-60LF and 77317-812-60LF are supplied in bag packaging. Packaging selection should align with assembly process requirements.

Q: Does the contact length difference between substitute parts affect board compatibility?

A: Contact length specifications vary across substitute parts. The M20-9953045 specifies 0.240" (6.10mm) mating contact length and 0.118" (3.00mm) post length. Preci-Dip 892 Series maintains identical post length (0.118" / 3.00mm) with mating contact lengths of 0.236" (6.00mm) or 0.276" (7.00mm). Amphenol ICC BERGSTIK® Series specifies 0.268" (6.80mm) mating contact length with 0.120" (3.05mm) post length. These variations may affect mating depth and board layout. Board design should accommodate the selected substitute part's contact geometry.

Q: Which substitute parts maintain ROHS3 compliance like the original M20-9953045?

A: All Preci-Dip 892 Series parts (892-18-060-20-001101, 892-18-060-20-002101, 892-70-060-20-001101, 892-70-060-20-002101, 892-80-060-20-001101) are ROHS3 Compliant. Amphenol ICC BERGSTIK® Series (77317-112-60LF, 77317-412-60LF, 77317-812-60LF) are RoHS Compliant. Amphenol ICC BERGSTIK® II Series compliance status is not specified in the provided data.
