Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-103361-8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Pitch spacing (0.100" / 2.54mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact length - mating (0.240" / 6.10mm)
• Contact length - post (0.110" / 2.79mm)
• Insulation height (0.214" / 5.44mm)
• Contact shape (Square)
• Termination method (Solder)

Material & Certification Parameters:

• Contact material (Phosphor Bronze)
• Insulation material (Thermoplastic)
• Material flammability rating (UL94 V-0)
• Series designation (AMPMODU Mod II)

Substitute parts must maintain identical values across all listed parameters to ensure functional and mechanical interchangeability within existing designs.

Parameter Comparison

Engineering Selection Recommendations

The 6-103361-8 serves as the direct substitute for the obsolete 1-103361-8. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring functional interchangeability.

Product Status Consideration: The 1-103361-8 carries obsolete status, while the 6-103361-8 is active. Selection of the 6-103361-8 ensures ongoing availability and supply chain continuity.

Compliance Differentiation: The primary distinction between these parts is regulatory compliance. The 1-103361-8 is RoHS non-compliant with tin-lead post finish. The 6-103361-8 is ROHS3 compliant with pure tin post finish. For applications subject to RoHS3 requirements or environmental regulations, the 6-103361-8 is the appropriate selection. For legacy systems with no RoHS compliance mandate, either part functions identically.

Packaging: The 6-103361-8 is supplied in tube packaging, whereas the 1-103361-8 packaging specification is not provided. Tube packaging is standard for this connector category and presents no compatibility issues.

Both parts share identical contact finish specifications for mating surfaces (gold plating at 30.0µin), operating temperature range, current rating, and mechanical dimensions. The connector maintains full compatibility with existing mating receptacles and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 6-103361-8 directly replace the 1-103361-8 in existing designs?

A: Yes. The 6-103361-8 maintains identical electrical and mechanical specifications. All critical parameters including connector type, position count, pitch spacing, mounting configuration, contact dimensions, and current rating are equivalent. Direct substitution is functionally compatible.

Q: What is the difference between the tin-lead finish on the 1-103361-8 and the tin finish on the 6-103361-8?

A: The 1-103361-8 features tin-lead (Sn-Pb) post finish, while the 6-103361-8 features pure tin (Sn) post finish. Both maintain the same finish thickness of 100.0µin (2.54µm). The tin finish on the 6-103361-8 reflects RoHS3 compliance requirements that restrict lead content. For solder joint formation and electrical performance, both finishes are functionally equivalent in standard PCB assembly processes.

Q: Why is the 1-103361-8 marked as obsolete?

A: The 1-103361-8 carries obsolete status due to regulatory evolution toward RoHS compliance. The 6-103361-8 represents the current production equivalent with updated material compliance. Obsolete designation indicates the part is no longer manufactured; the 6-103361-8 is the active replacement.

Q: Are there any mechanical compatibility issues when substituting the 6-103361-8 for the 1-103361-8?

A: No. Both connectors share identical mechanical specifications: 20-position, 0.100" pitch, through-hole right-angle mounting, shrouded 4-wall construction, and all contact dimensions. PCB footprints and mating receptacles are fully compatible.

Q: Does the tube packaging of the 6-103361-8 affect compatibility?

A: No. Packaging format affects only handling and storage logistics, not electrical or mechanical function. Tube packaging is standard for this connector series and presents no compatibility concerns for assembly or installation.

Q: What is the current rating for both connectors?

A: Both the 1-103361-8 and 6-103361-8 are rated for 3A per contact. This specification is identical across both parts.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both connectors operate across -65°C to 105°C. Temperature specifications are identical.

Q: Which part should be selected for new designs?

A: The 6-103361-8 is the appropriate selection for new designs. It is active in production, ROHS3 compliant, and maintains full compatibility with the legacy 1-103361-8 specification. Active product status ensures long-term availability and supply chain reliability.
