Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS04715B is determined by the following critical parameters:

Primary Compatibility Criteria:

4-position configuration with 0.197" (5.00mm) pitch
Plug type with female sockets
Free-hanging in-line mounting
Screw termination method
UL 300V minimum voltage rating
Wire gauge support within 12-24 AWG range
UL94 V-0 flammability rating
Active product status with RoHS3 compliance

Allowable Variations:

Wire entry orientation (270°, 90°, or other angles) may differ based on application layout requirements
Termination mechanism refinement (standard screw vs. rising cage clamp) is acceptable when torque specifications remain compatible
Housing material composition (brass vs. polyamide/nylon) does not affect electrical substitution when flammability ratings match
Wire gauge upper range extension (to 30 AWG) provides broader compatibility without compromising the 12-24 AWG minimum requirement

The identified substitutes maintain these core parameters while accommodating specific design variations.

Engineering Selection Recommendations

OSTTS04715B (Primary Part): Maintains original design specifications with 270° wire entry orientation and standard screw termination. Suitable for applications where the exact original configuration is required. Active product status ensures continued availability and support.

1792032 (Phoenix Contact - 90° Wire Entry): Functionally equivalent with 90° wire entry orientation instead of 270°. Provides rising cage clamp termination with enhanced wire retention features. Supports extended wire gauge range (12-30 AWG) and higher torque specification (0.5-0.6 Nm). Select this substitute when 90° wire entry orientation aligns with circuit board or enclosure layout requirements. Active product status and full RoHS3 compliance maintained.

1826432 (Phoenix Contact - 270° Wire Entry): Direct functional equivalent with matching 270° wire entry orientation. Provides rising cage clamp termination with non-wire side retention latches. Supports extended wire gauge range (12-30 AWG) and higher torque specification (0.5-0.6 Nm). Housing material differs (polyamide/nylon vs. brass) but maintains UL94 V-0 flammability rating. Black housing color differs from original green. Select this substitute when 270° orientation is required and rising cage clamp termination is acceptable. Active product status and full RoHS3 compliance maintained.

All three parts maintain UL 300V rating, UL94 V-0 flammability compliance, and Active product status with RoHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can 1792032 or 1826432 be used as direct replacements for OSTTS04715B?

A: Both Phoenix Contact parts are functionally equivalent within the scope of 4-position, 5.00mm pitch terminal block plugs with female sockets and free-hanging in-line mounting. The 1826432 maintains the 270° wire entry orientation of the original part. The 1792032 differs in wire entry angle (90°) and should be selected only when this orientation matches application requirements. Both support the 12-24 AWG wire gauge range of the original part and maintain UL 300V and UL94 V-0 specifications.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: The OSTTS04715B uses standard screw termination with 0.4 Nm torque specification. The Phoenix Contact substitutes (1792032 and 1826432) employ rising cage clamp termination with 0.5-0.6 Nm torque specification. Both methods provide secure wire connection; rising cage clamp offers enhanced wire retention features. Torque adjustment is required when switching between these termination styles.

Q: Are there wire gauge compatibility differences between the original part and substitutes?

A: The OSTTS04715B supports 12-24 AWG (0.34-2.5mm²). Both Phoenix Contact substitutes support 12-30 AWG (0.2-2.5mm²), providing extended range capability. The original 12-24 AWG range is fully contained within the substitute range, ensuring compatibility for existing wire specifications.

Q: Does housing material affect electrical performance or substitution eligibility?

A: The OSTTS04715B uses brass housing; the 1826432 uses polyamide (PA) nylon housing. Both maintain UL94 V-0 flammability rating and support identical electrical specifications (UL 300V, 4-position, 5.00mm pitch). Housing material does not affect electrical substitution eligibility when flammability ratings match.

Q: What is the significance of wire entry orientation (270° vs. 90°)?

A: Wire entry orientation determines the physical angle at which wires connect to the terminal block. The OSTTS04715B and 1826432 both feature 270° orientation. The 1792032 features 90° orientation. Selection depends on circuit board layout and enclosure design. Orientation does not affect electrical performance but must align with physical installation requirements.

Q: Are all three parts RoHS3 compliant and currently active?

A: Yes. The OSTTS04715B, 1792032, and 1826432 all maintain Active product status and full RoHS3 compliance. All parts carry unlimited moisture sensitivity rating (MSL 1) and REACH Unaffected status.
