TE Connectivity 2-1776489-2 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-1776489-2 is a 22-position terminal block header with male pins, unshrouded design, and 0.197" (5.00mm) vertical pitch. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The part features solder termination, through-hole mounting, and is rated for 10 A at 250 V (UL). Substitute parts must maintain electrical and mechanical compatibility while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-1776489-2 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Number of positions: 22
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Type: Header, Male Pins, Unshrouded
• Mounting method: Through Hole / Solder
• Contact tail length: 0.138" (3.50mm)
• Insulation height: 0.079" (2.00mm)

Electrical Compatibility Parameters:

• Current rating (UL): 10 A minimum
• Voltage rating (UL): 250 V minimum
• Contact material: Brass
• Contact mating finish: Tin

Compliance Parameters:

• Material flammability: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these critical parameters. Variations in housing material, operating temperature range, and RoHS/REACH compliance status do not affect functional substitution but are documented for design and procurement considerations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Assmann A-TB500-OP22

The Assmann A-TB500-OP22 is the preferred substitute for the TE Connectivity 2-1776489-2. This part maintains identical mechanical dimensions (22 positions, 5.00mm pitch, 0.138" contact tail length, 0.079" insulation height) and electrical ratings (10 A, 300 V UL). The A-TB500-OP22 is active in production status and ROHS3 compliant, providing long-term supply assurance. Operating temperature range extends to 115°C, exceeding the original part specification.

Secondary Substitutes: On Shore OSTOP220100 and OSTOP220200

The On Shore OSTOP220100 and OSTOP220200 provide functional equivalence with identical position count, pitch, and electrical ratings. Both parts are active and ROHS3 compliant. The OSTOP220100 features a longer contact tail (0.169" vs. 0.138"), which may require PCB layout verification. The OSTOP220200 maintains the original contact tail length (0.138") but has increased insulation height (0.138" vs. 0.079"), requiring clearance validation. Both parts are suitable for applications where the original TE Connectivity part is no longer available.

Alternative Substitute: On Shore OSTOP220000

The On Shore OSTOP220000 maintains core electrical and mechanical compatibility but features increased insulation height (0.138" vs. 0.079"), requiring design verification for board-level clearance. This part is active and ROHS3 compliant.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original TE Connectivity part carries "Not applicable" RoHS status due to obsolescence. Substitute parts provide improved compliance posture for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can the Assmann A-TB500-OP22 directly replace the TE Connectivity 2-1776489-2 without PCB modification?

A: The Assmann A-TB500-OP22 maintains identical contact tail length (0.138") and insulation height (0.079"), enabling direct PCB substitution. No layout modifications are required.

Q: What is the difference between the On Shore OSTOP220100 and OSTOP220200?

A: The OSTOP220100 features a longer contact tail (0.169" vs. 0.138") and standard insulation height (0.079"). The OSTOP220200 maintains the original contact tail length (0.138") but has increased insulation height (0.138"). Selection depends on PCB hole depth and clearance requirements.

Q: Are all substitute parts rated for the same electrical specifications?

A: All substitute parts are rated for 10 A current (UL) and 300 V voltage (UL), exceeding the original part's 250 V rating. Electrical compatibility is confirmed across all substitutes.

Q: Which substitute part offers the best long-term availability?

A: The Assmann A-TB500-OP22 and On Shore OSTOP series parts are all active in production status. Current inventory levels show OSTOP220200 (1076 Pcs) and OSTOP220100 (1057 Pcs) with highest stock. Selection should consider both current availability and manufacturer production roadmap.

Q: Do the substitute parts meet RoHS and REACH compliance?

A: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production.

Q: What is the impact of different insulation heights on board-level integration?

A: Insulation height affects the vertical clearance above the PCB. The original part and Assmann A-TB500-OP22 feature 0.079" insulation height. On Shore OSTOP220000 and OSTOP220200 feature 0.138" insulation height, requiring verification of available clearance in the application enclosure.

Q: Can multiple substitute parts be used interchangeably within the same assembly?

A: Mechanical differences (contact tail length and insulation height variations) between substitute parts require consistent selection within a single assembly to maintain uniform board-level geometry and clearance characteristics.
