RASH712 Equivalent & Substitute Parts

Part Overview

The RASH712 is a power barrel connector jack manufactured by Switchcraft Inc., designed for 2.5mm ID × 5.5mm OD applications. This surface mount, right-angle connector features solder termination and accommodates 5A current with a single normally closed internal switch across 3 contacts. The RASH712 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RASH712 is determined by strict equivalence across the following critical parameters: connector type (jack), gender (male), mating diameter (2.50mm ID × 5.50mm OD), contact configuration (3 contacts, 2 conductors), internal switch specification (single switch, normally closed), mounting orientation (right angle), termination method (solder), current rating (5A), shielding (unshielded), housing material (thermoplastic), contact material (brass), and body color (black).

The RASH712X qualifies as a direct substitute based on full alignment with these parameters. The primary distinction is mounting type: the RASH712 supports both surface mount and through-hole configurations, while the RASH712X is through-hole only. This difference does not preclude substitution in applications where through-hole mounting is acceptable.

Engineering Selection Recommendations

The RASH712X is the active equivalent for the obsolete RASH712. Selection of the RASH712X is supported by: (1) active product status ensuring ongoing availability and supply chain stability, (2) ROHS3 compliance meeting current regulatory requirements, and (3) full electrical and mechanical parameter equivalence with the RASH712.

The transition from tin to silver contact plating in the RASH712X represents an improvement in contact reliability and corrosion resistance. The through-hole-only mounting configuration of the RASH712X requires PCB layout modification if the original design utilized surface mount positioning; however, electrical and mechanical function remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the RASH712X directly replace the RASH712 in existing designs? A: The RASH712X provides full electrical and mechanical equivalence. PCB layout modification is required only if the original design specified surface mount positioning, as the RASH712X supports through-hole mounting exclusively.

Q: What is the significance of the contact plating change from tin to silver? A: Silver plating provides superior contact reliability and corrosion resistance compared to tin plating. This change enhances long-term performance and is not a limitation for substitution.

Q: Does the RASH712X meet current regulatory compliance standards? A: Yes. The RASH712X is ROHS3 compliant, meeting current environmental and regulatory requirements. The RASH712 is RoHS non-compliant and does not meet modern standards.

Q: Are there any current rating or electrical performance differences? A: No. Both parts maintain a 5A current rating and identical electrical specifications across all provided parameters.

Q: What packaging is available for the RASH712X? A: The RASH712X is supplied in bulk packaging with 6,746 units currently in stock.
