TE Connectivity 104076-8 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 104076-8 is a shrouded rectangular connector header designed for through-hole mounting in board-to-board and cable applications. This component features 100 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing and is part of the AMPMODU System 50 series. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead plated posts for solder termination.

The 104076-8 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support, maintenance, and procurement purposes. Active substitute components maintain identical electrical and mechanical specifications while offering current manufacturing availability and updated compliance certifications.

Substitute Part Grouping Explanation

Substitution of the obsolete 104076-8 with the active equivalent 5-104076-8 is based on strict electrical and mechanical parameter equivalence. Both components share identical specifications across all critical functional parameters that determine connector compatibility and performance:

Matching Parameters:

• Connector type, contact type, and contact shape
• Position count (100) and row configuration (2 rows)
• Mating pitch (0.050" / 1.27mm) and row spacing (0.100" / 2.54mm)
• Through-hole mounting and solder termination
• Shrouding configuration (Shrouded - 3 Wall)
• Push-pull fastening mechanism
• Contact dimensions and materials
• Operating temperature range (-65°C ~ 105°C)
• Voltage rating (30VAC)
• Flammability rating (UL94 V-0)
• AMPMODU System 50 series designation

The primary distinction between these parts is product status and compliance certification. The 5-104076-8 represents the current active production variant with updated RoHS3 compliance, whereas the 104076-8 is obsolete and RoHS non-compliant. The substitute maintains full functional and physical interchangeability for all applications.

Parameter Comparison

Engineering Selection Recommendations

The 5-104076-8 serves as the direct active equivalent for the obsolete 104076-8 rectangular connector header. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 104076-8 is classified as obsolete, limiting long-term procurement viability and manufacturing support. The 5-104076-8 maintains active production status, ensuring continued availability and supply chain reliability.

Compliance Certification: The 5-104076-8 achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets. The original 104076-8 is RoHS non-compliant and does not satisfy modern environmental and material restriction directives.

Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, pitch spacing, termination method, and operating characteristics. The components are fully interchangeable in existing designs without modification to PCB layouts, mating connectors, or assembly procedures.

Contact Finish Variation: The 5-104076-8 utilizes tin-plated posts compared to the tin-lead plating of the 104076-8. This change reflects industry transition away from lead-based materials and does not compromise solder joint reliability or electrical performance within the specified operating parameters.

For new designs and ongoing production, the 5-104076-8 is the appropriate selection. For legacy system maintenance requiring exact historical specifications, the 104076-8 remains available in current inventory (965 pieces) pending stock depletion.

Frequently Asked Questions (FAQ)

Q: Are the 104076-8 and 5-104076-8 physically interchangeable?

A: Yes. Both connectors share identical dimensions, mounting configurations, and contact arrangements. The 100-position, 2-row header with 0.050" pitch and through-hole solder termination allows direct substitution without PCB redesign or mechanical modification.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 104076-8 uses tin-lead plating on the solder posts, while the 5-104076-8 uses tin plating. Both finishes provide equivalent solder wettability and joint reliability. The tin finish reflects industry compliance with lead-free manufacturing standards and does not affect electrical performance or mechanical compatibility.

Q: Why is the 104076-8 classified as obsolete?

A: Obsolescence reflects TE Connectivity's discontinuation of this product line in favor of the updated 5-104076-8 variant. The substitute maintains all functional specifications while incorporating current compliance certifications and manufacturing processes.

Q: Does the RoHS3 compliance of the 5-104076-8 affect compatibility?

A: No. RoHS3 compliance indicates adherence to material restriction directives and does not alter electrical or mechanical performance. The compliance status is a regulatory and procurement consideration, not a functional parameter.

Q: Can the 104076-8 be used in new designs?

A: While the 104076-8 remains available in inventory, new designs should specify the 5-104076-8 to ensure long-term supply chain support and compliance with current regulatory requirements. The obsolete status of the 104076-8 creates risk for future procurement and manufacturing support.

Q: What packaging is available for the substitute part?

A: The 5-104076-8 is supplied in tube packaging. The original 104076-8 packaging specification was not provided in the technical documentation.

Q: Are there any temperature or voltage limitations when substituting these parts?

A: No. Both connectors operate across the identical temperature range (-65°C ~ 105°C) and voltage rating (30VAC). All thermal and electrical specifications remain unchanged between the main part and substitute.

Q: What applications are supported by the 5-104076-8?

A: The substitute part is rated for automotive, general purpose, medical, and telecommunications applications, matching the application scope of the original 104076-8.
