Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2178713-4 is based on strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: Ribbon Cable, DIP Header
• Number of positions: 4
• Cable pitch: 0.050" (1.27mm)
• Board-side pitch: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Cable termination method: IDC
• Contact finish: Tin

Mechanical Compatibility Parameters:

• Mounting type: Through Hole
• Series: Micro-MaTch
• Compliance certifications: ROHS3 Compliant, MSL 1

The substitute parts 215570-4 and 7-215570-4 satisfy all critical electrical and mechanical parameters. Both are active products within the Micro-MaTch series with identical pitch specifications, position count, and termination methodology. The primary differences are color designation (red versus black) and wire gauge specification (28 AWG stranded or solid), which do not affect connector interface compatibility at the board level.

Parameter Comparison

Engineering Selection Recommendations

Both 215570-4 and 7-215570-4 are qualified substitutes for the obsolete 2178713-4 based on electrical and mechanical parameter alignment. Selection between the two substitute options should be based on supply chain availability and packaging requirements, as both parts are active products with identical electrical specifications and compliance certifications.

The substitute parts incorporate press-fit mounting capability in addition to through-hole mounting, providing enhanced installation flexibility. Both maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

The color difference (red versus black) and explicit wire gauge specification (28 AWG stranded or solid) in the substitute parts do not affect connector interface compatibility at the board level. These characteristics relate to cable assembly identification and wire handling properties rather than connector mating surfaces or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 215570-4 and 7-215570-4 electrically compatible with the 2178713-4?

A: Yes. Both substitute parts maintain identical electrical specifications including connector type, position count, pitch dimensions, row configuration, IDC termination method, and tin contact finish. These parameters define electrical compatibility at the connector interface.

Q: What is the difference between 215570-4 and 7-215570-4?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the REACH compliance status designation. Part 7-215570-4 is marked as REACH Unaffected, while 215570-4 is marked as Vendor Undefined. Both are ROHS3 compliant and suitable for equivalent applications.

Q: Why is the color different between the main part and substitutes?

A: The main part 2178713-4 is black, while substitutes 215570-4 and 7-215570-4 are red. Color designation is a visual identification characteristic and does not affect electrical or mechanical connector compatibility. Color selection is typically driven by cable assembly standards or system identification requirements.

Q: Does the 28 AWG wire gauge specification on the substitute parts affect compatibility?

A: No. The wire gauge specification on the substitute parts refers to the cable assembly configuration, not the connector interface. The connector mating surfaces and electrical performance remain identical. The 28 AWG specification indicates the wire size used in the ribbon cable assembly.

Q: What is the difference between through-hole and press-fit mounting?

A: The main part 2178713-4 specifies through-hole mounting. The substitute parts 215570-4 and 7-215570-4 support both through-hole and press-fit mounting options. Press-fit capability provides an additional installation method without affecting through-hole compatibility. Existing through-hole designs remain fully compatible.

Q: Are the substitute parts available in the same packaging as the main part?

A: The substitute parts are supplied in Cut Tape (CT) packaging. Packaging format does not affect connector electrical or mechanical performance and is determined by procurement and inventory management requirements.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the main part specifications. Both carry EAR99 ECCN and 8536.69.4040 HTSUS classifications.
