Substitute Part Grouping Explanation

Substitute parts for the 647346-5 are identified based on strict parametric equivalence within the SL-156 series. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 5
• Pitch: 0.156" (3.96mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Color: Natural
• Series: SL-156
• RoHS Status: RoHS Compliant
• MSL: 1 (Unlimited)

All substitute parts listed maintain these parameters, ensuring direct functional and mechanical compatibility. Substitutes differ only in base product number designation and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

647346-5 (Primary Part): Active product status with RoHS compliance and MSL 1 rating. Current inventory of 831 pieces supports standard procurement cycles.

640250-5 (Preferred Substitute): Active product with RoHS compliance, MSL 1 rating, and documented operating temperature range of -55°C to 105°C. Significantly higher inventory availability (56,845 pieces) provides extended lead time assurance and supply chain flexibility. Insulation material specified as Polyamide (PA), Nylon.

647401-5 (Secondary Substitute): Active product with RoHS compliance, MSL 1 rating, and documented operating temperature range of -55°C to 105°C. Moderate inventory availability (1,286 pieces). Insulation material specified as Polyamide (PA), Nylon.

All three parts maintain identical electrical and mechanical specifications within the SL-156 series. Selection between primary and substitute parts is determined by inventory availability, delivery requirements, and supply chain considerations rather than functional differences.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 640250-5 and 647401-5 electrically and mechanically compatible with 647346-5?

A: Yes. All three parts share identical specifications for connector type, contact type, number of positions, pitch, mounting type, contact termination, and fastening type. They are direct functional equivalents within the SL-156 series.

Q: What is the significance of the different base product numbers (647346, 640250, 647401)?

A: Base product numbers represent different part designations within TE Connectivity's catalog structure. The suffix "-5" indicates the 5-position configuration. Different base numbers do not indicate functional differences when all parametric specifications are identical.

Q: Do the substitute parts have documented operating temperature specifications?

A: Parts 640250-5 and 647401-5 specify an operating temperature range of -55°C to 105°C. The main part 647346-5 does not include operating temperature documentation in the provided specifications.

Q: What is the difference in insulation material between the main part and substitutes?

A: The main part 647346-5 does not specify insulation material. Substitute parts 640250-5 and 647401-5 specify Polyamide (PA), Nylon as the insulation material.

Q: Which substitute part should be selected based on inventory availability?

A: Part 640250-5 offers the highest inventory level at 56,845 pieces, providing the greatest supply assurance. Part 647401-5 provides 1,286 pieces as a secondary option. Selection depends on project lead time requirements and procurement strategy.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—647346-5, 640250-5, and 647401-5—are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical pitch (0.156"), position count (5), mounting type (free hanging in-line), and fastening mechanism (locking ramp) ensure direct interchangeability in applications designed for the SL-156 series 5-position receptacle housing.
