Substitute Part Grouping Explanation

Substitution eligibility for the 3M 951208-2520-AR-TP is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

Connector type: Header
Contact type: Male Pin
Number of positions: 8
Number of rows: 2
Pitch - mating: 0.079" (2.00mm)
Row spacing - mating: 0.079" (2.00mm)
Mounting type: Surface Mount
Termination: Solder
Style: Board to Board
Contact finish - mating: Gold
Contact finish - post: Tin
Material flammability rating: UL94 V-0

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact length, contact finish thickness, insulation height, and post material do not preclude functional substitution when the primary criteria are satisfied. Current rating and voltage rating differences are noted but do not eliminate substitution eligibility when the substitute part meets or exceeds the original specification.

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing support, addressing the obsolescence status of the 3M 951208-2520-AR-TP. Selection among substitutes should be based on the following factors:

Amphenol ICC 57202 Series (57202-F52-04LF, 57202-G52-04LF, 57202-S52-04LF, 57202-S52-04ULF): These parts are from the Minitek® 2.00mm series and offer RoHS compliance. Differentiation among these variants is determined by packaging format (Box, Bulk, Bag, Tube) and contact finish thickness specifications. All four variants are electrically and mechanically equivalent for board-to-board applications.

Sullins Connector Solutions NRPN042MAMP-RC and NRPN042MAMS-RC: These parts provide ROHS3 compliance and extended operating temperature range (-40°C ~ 105°C). The NRPN042MAMS-RC variant includes board guide features and is available in higher inventory quantities. Both Sullins parts feature brass contact material and gold post finish, distinguishing them from the Amphenol and original 3M specifications.

All substitute parts meet the core electrical and mechanical requirements for direct functional replacement. Current rating improvements (1A to 2A) and expanded temperature ranges in Sullins variants provide design margin benefits. RoHS and ROHS3 compliance certifications ensure regulatory alignment for new production.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 57202 series parts directly replace the 3M 951208-2520-AR-TP?

A: Yes. The 57202-F52-04LF, 57202-G52-04LF, 57202-S52-04LF, and 57202-S52-04ULF all match the critical electrical and mechanical parameters: 8-position, 2-row header with 0.079" (2.00mm) pitch, surface mount solder termination, gold-plated mating contacts, and tin-plated posts. Differences in contact finish thickness and packaging do not affect functional compatibility.

Q: What is the difference between the four Amphenol ICC 57202 variants?

A: The variants differ in packaging format and contact finish thickness. 57202-F52-04LF ships in Box packaging with 39.4µin (1.00µm) mating contact finish thickness. 57202-G52-04LF is supplied in Bulk with 30.0µin (0.76µm) finish. 57202-S52-04LF and 57202-S52-04ULF both feature 15.0µin (0.38µm) finish thickness, with the former in Bag packaging and the latter in Tube. All are electrically equivalent.

Q: How do the Sullins NRPN042 parts differ from the Amphenol alternatives?

A: The Sullins NRPN042MAMP-RC and NRPN042MAMS-RC use brass contact material with gold post finish, compared to copper alloy contacts with tin post finish in the Amphenol parts. Sullins parts also provide extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 105°C) and ROHS3 compliance. The NRPN042MAMS-RC includes board guide features. Contact length is 0.141" (3.60mm) versus 0.157" (4.00mm) in the original 3M part.

Q: Are all substitute parts RoHS compliant?

A: Yes. Amphenol ICC 57202 series parts are RoHS Compliant. Sullins NRPN042MAMP-RC and NRPN042MAMS-RC are ROHS3 Compliant. All meet current environmental and regulatory requirements for new production.

Q: What is the current rating difference, and does it affect substitution?

A: The original 3M part is rated at 1A, while all substitute parts are rated at 2A. This represents an improvement in current-carrying capacity and does not preclude substitution. The higher rating provides additional design margin for applications operating at or near the original 1A specification.

Q: Which substitute part offers the best inventory availability?

A: The Sullins NRPN042MAMS-RC offers the highest inventory level at 19,637 pieces in stock. Among Amphenol ICC parts, 57202-G52-04LF provides 1,885 pieces. Amphenol ICC 57202-F52-04LF and 57202-S52-04ULF offer 843 and 1,168 pieces respectively.
