RJ-6P102 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The RJ-6P102 is a 1 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based component features top adjustment with PC pin termination and is designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary RJ-6P102 becomes unavailable due to supply constraints, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for dimensional or form factor variations while maintaining electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RJ-6P102 is determined by strict electrical and mechanical parameter matching. All substitute parts must maintain identical specifications across the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions, packaging format (bulk vs. tube), and manufacturer identity do not affect electrical substitutability. RoHS compliance status and REACH classification may differ between substitutes and should be evaluated based on end-application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence to the RJ-6P102 across all critical parameters. Selection between substitutes should be based on the following factors:

RoHS Compliance: The RJ-6P102, 25PR1KLF, 3329H-1-102LF, 72PMR1KLF, 72PR1KLF, and 82PR1KLF are ROHS3 compliant. The 3329P-1-102 is RoHS non-compliant and should be selected only when regulatory requirements do not mandate RoHS compliance.

REACH Status: The 3329H-1-102LF and 3329P-1-102 are REACH Affected. The RJ-6P102, 25PR1KLF, 72PMR1KLF, 72PR1KLF, and 82PR1KLF are REACH Unaffected. Applications subject to REACH regulations should prioritize REACH Unaffected parts.

Packaging Format: Bulk packaging is available in RJ-6P102, 72PMR1KLF, 72PR1KLF, and 82PR1KLF. Tube packaging is available in 25PR1KLF, 3329H-1-102LF, and 3329P-1-102. Manufacturing process requirements may dictate packaging preference.

Physical Dimensions: Dimensional variations exist across substitutes. The RJ-6P102 features a round 0.276" diameter form factor. Compact alternatives include the 3329H-1-102LF and 82PR1KLF (0.250" diameter round), 25PR1KLF (0.270" x 0.270" square), and larger options include 72PMR1KLF and 72PR1KLF (0.375" x 0.375" square). PCB layout constraints should guide selection.

Inventory Availability: The 25PR1KLF offers the highest inventory level (12,299 pcs), followed by 82PR1KLF (2,806 pcs) and 72PMR1KLF (2,034 pcs). Immediate availability requirements may favor these options.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RJ-6P102 with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical electrical specifications (1 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, PC pin termination). Electrical substitution is direct. Physical layout considerations may apply due to dimensional differences.

Q: What is the primary difference between the RJ-6P102 and its substitutes?

A: The primary differences are manufacturer identity, physical form factor (round vs. square), packaging format (bulk vs. tube), and regulatory compliance status. All electrical and functional parameters are identical.

Q: Are there any compatibility issues with different packaging formats?

A: Packaging format (bulk vs. tube) affects only the supply and handling method, not component compatibility. Bulk packaging typically suits high-volume manufacturing, while tube packaging is common for lower-volume or manual assembly processes. Select based on your manufacturing workflow.

Q: Which substitute should I choose if RoHS compliance is mandatory?

A: Select from 25PR1KLF, 3329H-1-102LF, 72PMR1KLF, 72PR1KLF, or 82PR1KLF. All are RoHS compliant. The 3329P-1-102 is RoHS non-compliant and must be avoided in RoHS-regulated applications.

Q: Does REACH compliance affect my component selection?

A: REACH Affected status applies to 3329H-1-102LF and 3329P-1-102. If your application or end market is subject to REACH regulations, prioritize REACH Unaffected parts: RJ-6P102, 25PR1KLF, 72PMR1KLF, 72PR1KLF, or 82PR1KLF.

Q: Can I use the larger form factor substitutes (72PMR1KLF, 72PR1KLF) in space-constrained designs?

A: The 72PMR1KLF and 72PR1KLF feature 0.375" x 0.375" square form factors, significantly larger than the RJ-6P102 (0.276" round). These are suitable only if PCB layout permits the increased footprint. For space-constrained applications, consider the 3329H-1-102LF, 82PR1KLF (0.250" round), or 25PR1KLF (0.270" x 0.270" square).

Q: What is the difference between the Bourns 3329H-1-102LF and 3329P-1-102?

A: Both are Bourns Trimpot® 3329 series with identical electrical specifications and 0.250" round form factors. The primary difference is RoHS compliance: 3329H-1-102LF is ROHS3 compliant, while 3329P-1-102 is RoHS non-compliant. Select based on regulatory requirements.
