OSTHP075050 Equivalent & Substitute Parts

Part Overview

The OSTHP075050 is a 7-position terminal block plug with female sockets manufactured by On-Shore Technology. This component features a 0.200" (5.08mm) pitch and is designed for free-hanging in-line mounting applications with IDC termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHP075050 is based on strict alignment of the following critical parameters:

• 7-position configuration with 0.200" (5.08mm) pitch spacing
• Female socket plug type with IDC termination
• Free-hanging in-line mounting orientation
• Wire gauge compatibility: 18-22 AWG
• Voltage rating: 300 V UL minimum
• Flammability compliance: UL94 V-0
• Operating temperature range accommodation

The Phoenix Contact 1883307 meets all these core substitution criteria. While this substitute introduces additional specifications (180° wire entry, tin contact finish, retention latches), these represent functional enhancements rather than deviations from the base electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The OSTHP075050 is classified as obsolete. The Phoenix Contact 1883307 is an active product with current manufacturing support and inventory availability (1100 pcs in stock versus 935 pcs for the obsolete part).

Both components maintain identical compliance certifications: UL94 V-0 flammability rating, RoHS compliance, and EAR99 export classification. The substitute part carries additional certifications including IEC current rating (10A) and IEC voltage rating (1 kV), which exceed the UL specifications of the original part.

For new designs or system replacements, the 1883307 is the appropriate selection due to active product status and enhanced electrical specifications. For legacy system maintenance requiring exact form-factor compatibility, the OSTHP075050 remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1883307 directly replace the OSTHP075050 in existing assemblies?

A: Yes. Both components share identical pitch (5.08mm), position count (7), socket type (female), termination method (IDC), and mounting configuration (free-hanging in-line). Wire gauge compatibility (18-22 AWG) and voltage rating (300V UL) are matched.

Q: What is the significance of the 180° wire entry specification on the 1883307?

A: The 180° wire entry indicates the direction of cable approach to the plug. This is a functional enhancement that does not prevent substitution but may require cable routing adjustment in space-constrained applications.

Q: Are there differences in contact materials between these parts?

A: The 1883307 specifies tin contact mating finish. The OSTHP075050 does not provide contact material specifications in available documentation. Both maintain UL94 V-0 housing material compliance.

Q: Does the retention latch feature on the 1883307 affect compatibility?

A: No. Retention latches on the non-wire side enhance mechanical stability during mating but do not affect electrical or mechanical substitution compatibility with the original part.

Q: What is the inventory status for each part?

A: OSTHP075050: 935 pcs (obsolete status). 1883307: 1100 pcs (active product). For new procurement, the 1883307 is recommended due to active manufacturing support.
