Key Parameters

Substitute Part Grouping Explanation

Substitution of the 176376-4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for connector position count, pitch, row configuration, mounting methodology, contact material and finish, stacking height, and board engagement characteristics. The 5176376-4 qualifies as a direct substitute based on complete parameter alignment across all these criteria. The primary distinction between the main part and its substitute is product status and regulatory compliance posture, not functional or dimensional characteristics.

Key Parameters Determining Substitution:

• Number of Positions: 100
• Pitch: 0.050" (1.27mm)
• Number of Rows: 2
• Connector Type: Receptacle, Outer Shroud Contacts
• Mounting Type: Through Hole
• Contact Finish: Gold at 11.8µin (0.30µm)
• Mated Stacking Height: 16mm
• Height Above Board: 0.531" (13.49mm)
• Series: Free Height (FH)
• Features: Board Guide

Parameter Comparison

Engineering Selection Recommendations

The 5176376-4 is the direct functional equivalent to the obsolete 176376-4. All electrical and mechanical parameters are identical, ensuring complete interchangeability in circuit board designs and assembly processes. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain reliability.

The 5176376-4 carries ROHS3 compliance, whereas the original 176376-4 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. The substitute part is supplied in bulk packaging, which may differ from the original part's packaging configuration but does not affect functional performance or compatibility.

Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent export control and tariff treatment. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are the 176376-4 and 5176376-4 electrically and mechanically interchangeable?

A: Yes. Both parts are 100-position rectangular connectors with identical pitch (0.050"), row configuration (2 rows), contact finish (gold at 11.8µin), mounting type (through hole), and all dimensional specifications including mated stacking height (16mm) and height above board (0.531"). They are direct functional equivalents.

Q: What is the primary reason to transition from 176376-4 to 5176376-4?

A: The 176376-4 is classified as obsolete, which creates supply chain risk. The 5176376-4 is an active product with confirmed inventory availability, ensuring continued sourcing capability for production and new designs.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance status does not affect electrical or mechanical compatibility. The difference reflects manufacturing process compliance with environmental regulations. The ROHS3 compliance of the 5176376-4 is advantageous for applications subject to RoHS requirements.

Q: Is the bulk packaging of the 5176376-4 a limitation?

A: Bulk packaging is a supply format difference, not a functional limitation. The connector itself is identical. Bulk packaging may require different handling procedures during receiving and inventory management but does not affect the part's performance or compatibility.

Q: Can the 5176376-4 be used as a direct replacement in existing designs?

A: Yes. The 5176376-4 maintains complete parameter equivalence with the 176376-4 across all critical specifications. No design modifications are required for substitution.

Q: Are there any differences in contact finish quality between the two parts?

A: No. Both parts specify identical gold contact finish at 11.8µin (0.30µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: What is the moisture sensitivity classification for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling procedures are sufficient without special environmental controls.
