Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55D4752FRSL is determined by the following critical parameters: resistance value (47.5 kOhms), power rating (0.125W), package type (Axial), operating temperature range (-65°C to 175°C), composition (Metal Film), and series compliance (MIL-R-10509/7, RN55). Substitute parts must maintain identical resistance, power rating, physical dimensions, and temperature operating range. Variations in tolerance, temperature coefficient, and packaging format (Tape & Reel, Cut Tape, Bulk) are permitted when the core electrical and mechanical specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RN55D4752FRSL, RN55D4752FRE6, and RN55E4752BB14—are active production components from Vishay Dale within the military-grade RN55 series. Selection between these parts should be based on packaging requirements and tolerance specifications.

RN55D4752FRSL (Tape & Reel packaging) is suitable for automated assembly processes requiring continuous reel supply. RN55D4752FRE6 (Cut Tape packaging) accommodates mixed-component orders and manual assembly workflows. RN55E4752BB14 (Bulk packaging) provides cost-effective procurement for high-volume applications and offers enhanced tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C) compared to the ±1% tolerance and ±100ppm/°C coefficient of the main part.

All parts maintain identical electrical performance in core parameters: 47.5 kOhms resistance, 0.125W power rating, metal film composition, and -65°C to 175°C operating temperature range. Compliance status remains consistent across all three parts: RoHS non-compliant and REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can RN55D4752FRE6 be used as a direct replacement for RN55D4752FRSL?

A: Yes. Both parts are parametric equivalents with identical resistance (47.5 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The only difference is packaging format: Tape & Reel versus Cut Tape. Electrical performance and mechanical fit are identical.

Q: What is the advantage of RN55E4752BB14 over RN55D4752FRSL?

A: RN55E4752BB14 offers tighter tolerance (±0.1% versus ±1%) and superior temperature stability (±25ppm/°C versus ±100ppm/°C). These enhancements provide improved circuit accuracy and reduced drift over temperature variations. All other electrical and mechanical specifications remain equivalent.

Q: Are there any compliance differences between these parts?

A: No. All three parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Military series designation (MIL-R-10509/7, RN55) and features (Flame Retardant Coating, Military, Moisture Resistant, Safety) are consistent across all parts.

Q: Which packaging format should I select for my application?

A: Tape & Reel (RN55D4752FRSL) is optimized for automated pick-and-place assembly. Cut Tape (RN55D4752FRE6) suits mixed-component procurement and manual assembly. Bulk (RN55E4752BB14) is appropriate for high-volume applications where packaging efficiency is prioritized.

Q: Can these parts be used interchangeably in military applications?

A: Yes. All three parts are certified to MIL-R-10509/7 and belong to the military-grade RN55 series. They maintain identical operating temperature range (-65°C to 175°C) and feature military-grade specifications including flame retardant coating and moisture resistance.
