P20-0345R Equivalent & Substitute Parts

Part Overview

The P20-0345R is a 3-position spring piston connector manufactured by Harwin Inc., designed for surface mount applications in the HotShoe series. This rectangular connector features brass contacts with gold plating and is classified as obsolete. Due to its obsolete status, equivalent substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P20-0345R is determined by the following critical parameters:

• Contact Type: Sleeve & Plunger (Pogo Pins) — all substitute parts maintain this contact architecture
• Contact Material & Finish: Brass with gold plating — all substitutes use identical materials with enhanced finish thickness (16.0µin vs. 10.0µin)
• Current Rating: 2A — consistent across all substitute options
• Mating Cycles: 10,000 — standardized performance specification
• Operating Temperature Range: -40°C ~ 85°C — maintained across all substitutes
• Compliance: ROHS3, REACH Unaffected, MSL 1 — all substitutes meet identical regulatory requirements

Substitutes are grouped into two mounting categories: Surface Mount (SMD) and Through Hole (T/H), with variations in working height and plunger diameter to accommodate different application requirements.

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Harwin Inc. and maintain full compliance with ROHS3 and REACH requirements. Selection among substitutes depends on mounting methodology and mechanical envelope constraints:

Surface Mount Options:

• P70-1000045R: Compact working height (0.106" – 0.118"), suitable for space-constrained applications
• P70-1010045R: Extended working height (0.146" – 0.165"), accommodates thicker PCB assemblies
• P70-5100045: Miniature plunger diameter (0.024"), designed for high-density contact arrays

Through Hole Options:

• P70-2000045R: Standard working height (0.112" – 0.122"), conventional through-hole mounting
• P70-2010045R: Extended working height (0.152" – 0.165"), accommodates variable board thickness

All substitutes provide enhanced contact finish thickness (16.0µin) compared to the original P20-0345R (10.0µin), improving durability and contact reliability.

Frequently Asked Questions (FAQ)

Q: Can P70 series contacts directly replace the P20-0345R connector? A: The P70 series are individual contact components, not complete connectors. They are functionally equivalent in contact architecture, material composition, and electrical performance. Integration into your assembly design requires mechanical accommodation of the individual contact form factor.

Q: What is the difference between SMD and T/H variants? A: Surface Mount (SMD) variants (P70-1000045R, P70-1010045R, P70-5100045) are designed for reflow soldering to PCB pads. Through Hole (T/H) variants (P70-2000045R, P70-2010045R) are designed for insertion into plated through holes. Selection depends on your PCB assembly process and design requirements.

Q: Why do substitute parts have thicker gold plating? A: The enhanced contact finish thickness (16.0µin vs. 10.0µin) on P70 series contacts provides improved wear resistance and contact reliability over extended mating cycles, representing a design improvement over the obsolete P20-0345R.

Q: Are all substitutes rated for the same current and temperature range? A: Yes. All substitute parts are rated for 2A current and operate across the -40°C to 85°C temperature range, maintaining electrical performance consistency with the original specification.

Q: What packaging options are available? A: P70-1000045R is supplied in Cut Tape (CT) & Digi-Reel format. P70-1010045R is supplied in Tape & Reel (TR). P70-2000045R and P70-2010045R are supplied in Cut Tape (CT). P70-5100045 is supplied in Bag format. Select based on your procurement and assembly requirements.

Q: Do all substitutes meet the same regulatory compliance? A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (unlimited), matching the compliance profile of the P20-0345R.
