Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1776148-5 is determined by the following critical parameters:

Primary Substitution Criteria:

• 5-position configuration with male pins
• Shrouded (4-side) design
• 90° right-angle orientation
• Through-hole or solder mounting capability
• 15 A current rating (UL)
• 300 V voltage rating (UL)
• Tin contact mating finish
• RoHS compliance status
• MSL 1 (Unlimited) moisture sensitivity

Secondary Compatibility Factors:

• Pitch tolerance: 0.197" (5.00mm) to 0.200" (5.08mm) are mechanically compatible within standard PCB design tolerances
• Operating temperature range: -40°C minimum and 110°C minimum required
• Housing material: Polyamide (PA), Nylon, or Thermoplastic acceptable
• Contact tail length and insulation height variations within standard mechanical envelope

The identified substitute parts (Phoenix Contact 5433697 and On Shore Technology Inc. OSTOQ055451) meet all primary substitution criteria and maintain electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1776148-5 (Original Part)

The TE Connectivity 1776148-5 maintains active product status with established supply chain availability (1051 pcs in stock). This component carries UL94 V-0 flammability certification and RoHS compliance. The through-hole mounting configuration with 0.126" (3.20mm) contact tail length and 0.341" (8.66mm) insulation height establishes the baseline mechanical envelope for this application class.

Phoenix Contact 5433697 (Primary Substitute)

The Phoenix Contact 5433697 provides direct electrical equivalence with 15 A (UL) and 300 V (UL) ratings. The BCH series component maintains identical shrouded 4-side male pin configuration with 90° right-angle orientation. The 0.200" (5.08mm) pitch represents a 0.003" (0.08mm) increase from the original specification, which falls within standard PCB design tolerances for 5-position terminal block applications. UL94 V-0 flammability rating and RoHS compliance are maintained. Higher inventory availability (1081 pcs) supports supply continuity. IEC ratings of 12 A and 400 V exceed UL requirements.

On Shore Technology Inc. OSTOQ055451 (Secondary Substitute)

The On Shore Technology OSTOQ055451 meets electrical requirements with 300 V (UL) rating and tin contact mating finish. The OSTOQ series maintains 5-position shrouded male pin configuration with 90° right-angle orientation. Operating temperature range extends to -40°C ~ 115°C, exceeding the original -40°C ~ 110°C specification. ROHS3 compliance and MSL 1 (Unlimited) rating are maintained. The 0.157" (4.00mm) contact tail length and 0.157" (4.00mm) insulation height represent significant dimensional variations from the original specification; mechanical compatibility requires PCB design verification. Highest inventory availability (2503 pcs) provides maximum supply security.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 5433697 be used as a direct replacement for the TE Connectivity 1776148-5?

A: The Phoenix Contact 5433697 is electrically and mechanically compatible. Both components feature 5-position shrouded male pin headers with 90° right-angle orientation, 15 A (UL) current rating, and 300 V (UL) voltage rating. The 0.003" (0.08mm) pitch difference (5.08mm vs. 5.00mm) is within standard PCB design tolerances for terminal block applications. Contact tail length and insulation height variations are minor (0.012" and 0.002" respectively) and do not affect standard mounting applications.

Q: What are the key differences between the On Shore Technology OSTOQ055451 and the original TE Connectivity part?

A: The OSTOQ055451 maintains electrical compatibility (300 V UL rating) and configuration (5-position shrouded male pins, 90° right-angle). Primary differences include: contact tail length of 0.157" (4.00mm) versus 0.126" (3.20mm), insulation height of 0.157" (4.00mm) versus 0.341" (8.66mm), and extended operating temperature range (-40°C ~ 115°C versus -40°C ~ 110°C). These dimensional variations require PCB design verification to confirm mechanical compatibility with existing mounting holes and clearances.

Q: Are all three parts RoHS compliant?

A: Yes. The TE Connectivity 1776148-5 and Phoenix Contact 5433697 carry RoHS Compliant certification. The On Shore Technology OSTOQ055451 carries ROHS3 Compliant certification. All three parts meet current RoHS requirements and are suitable for applications requiring RoHS compliance.

Q: What is the moisture sensitivity level (MSL) for these terminal blocks?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. These components do not require special storage or handling procedures related to moisture sensitivity.

Q: Do these parts have different current ratings?

A: The TE Connectivity 1776148-5 and Phoenix Contact 5433697 both carry 15 A (UL) current rating. The On Shore Technology OSTOQ055451 does not specify a UL current rating in the provided documentation. For applications requiring confirmed 15 A capacity, the TE Connectivity or Phoenix Contact parts are recommended.

Q: What is the pitch difference between these parts, and does it matter?

A: The TE Connectivity 1776148-5 has 0.197" (5.00mm) pitch, while both substitute parts have 0.200" (5.08mm) pitch. This 0.003" (0.08mm) difference is within standard PCB design tolerances for terminal block spacing and does not prevent direct substitution in typical applications. PCB layout verification is recommended for applications with tight spacing constraints.

Q: Which substitute part has the best inventory availability?

A: The On Shore Technology OSTOQ055451 has the highest inventory availability with 2503 pcs in stock, followed by Phoenix Contact 5433697 with 1081 pcs, and the original TE Connectivity 1776148-5 with 1051 pcs.

Q: Are there any flammability rating differences?

A: The TE Connectivity 1776148-5 and Phoenix Contact 5433697 both carry UL94 V-0 flammability certification. The On Shore Technology OSTOQ055451 does not specify a flammability rating in the provided documentation. For applications requiring confirmed UL94 V-0 compliance, the TE Connectivity or Phoenix Contact parts are recommended.
