Key Parameters

Substitute Part Grouping Explanation

Substitution logic for RMC1/8-8R2JTP is based on the following mandatory parameters:

Core Electrical Compatibility:

• Resistance value: 8.2 Ohms (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Package format: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (technology class match)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)

Tolerance Grades: Substitute parts are grouped into two tolerance classifications:

• ±5% Tolerance Group: Direct functional equivalents with identical tolerance specification (RC1206JR-078R2L, RMCF1206JT8R20)
• ±1% Tolerance Group: Enhanced accuracy substitutes with tighter tolerance specification (ERJ-8RQF8R2V, KTR18EZPF8R20, RC1206FR-078R2L, RMCF1206FT8R20)

Environmental & Certification Features: Substitute parts may include automotive AEC-Q200 certification, current sense capability, high voltage rating, or moisture-resistant construction. These features represent functional enhancements that do not restrict substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Tolerance Match (±5%): RC1206JR-078R2L and RMCF1206JT8R20 provide functional equivalence with identical ±5% tolerance specification. Both parts maintain Active product status and MSL 1 classification. RMCF1206JT8R20 includes automotive AEC-Q200 certification. RC1206JR-078R2L offers moisture-resistant construction. Selection between these parts depends on application requirements for automotive qualification or enhanced environmental protection.

Enhanced Tolerance Grade (±1%): ERJ-8RQF8R2V, KTR18EZPF8R20, RC1206FR-078R2L, and RMCF1206FT8R20 provide tighter tolerance specification at ±1%. All four parts maintain Active product status and MSL 1 classification. ERJ-8RQF8R2V and RMCF1206FT8R20 include automotive AEC-Q200 certification with current sense and general automotive features respectively. KTR18EZPF8R20 includes automotive AEC-Q200 certification with high voltage rating. RC1206FR-078R2L provides moisture-resistant construction without automotive certification. Selection among these parts depends on application requirements for automotive qualification, high voltage operation, or current sensing capability.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected. All parts maintain identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications. All parts are classified as Active product status with unlimited moisture sensitivity level.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8RQF8R2V replace RMC1/8-8R2JTP in any application?

A: ERJ-8RQF8R2V is electrically and mechanically compatible as a substitute. The part maintains 8.2 Ohm resistance, 0.25W power rating, 1206 package format, and -55°C ~ 155°C operating temperature range. ERJ-8RQF8R2V offers ±1% tolerance compared to the ±5% specification of RMC1/8-8R2JTP, representing improved accuracy. Automotive AEC-Q200 certification and current sense features are present in ERJ-8RQF8R2V but not in the original part. Applications requiring the original ±5% tolerance specification should confirm tolerance acceptance before substitution.

Q: What is the difference between ±5% and ±1% tolerance substitutes?

A: Tolerance specification defines the acceptable resistance value range at nominal conditions. RMC1/8-8R2JTP with ±5% tolerance permits resistance values between 7.79 Ohms and 8.61 Ohms. Substitute parts with ±1% tolerance (ERJ-8RQF8R2V, KTR18EZPF8R20, RC1206FR-078R2L, RMCF1206FT8R20) permit resistance values between 8.118 Ohms and 8.282 Ohms. Applications with strict circuit performance requirements may benefit from ±1% tolerance substitutes. Applications designed for ±5% tolerance acceptance do not require ±1% substitutes.

Q: Are all substitute parts automotive qualified?

A: Automotive AEC-Q200 certification is present in ERJ-8RQF8R2V, KTR18EZPF8R20, RMCF1206FT8R20, and RMCF1206JT8R20. RC1206FR-078R2L and RC1206JR-078R2L do not include automotive certification. Applications requiring automotive qualification must select from the AEC-Q200 certified substitute parts.

Q: Can substitute parts with higher power ratings be used?

A: All identified substitute parts maintain 0.25W power rating specification identical to RMC1/8-8R2JTP. No substitute parts with higher power ratings are included in this equivalency list.

Q: What is the significance of moisture-resistant construction in RC1206FR-078R2L and RC1206JR-078R2L?

A: Moisture-resistant construction is a feature enhancement that does not restrict substitution compatibility. Both RMC1/8-8R2JTP and the moisture-resistant substitutes maintain MSL 1 (Unlimited) classification. Moisture-resistant construction provides additional environmental protection in high-humidity applications but is not required for standard operating conditions.

Q: Are there physical dimension differences between substitute parts?

A: Physical dimensions vary slightly among substitute parts. RMC1/8-8R2JTP and RC1206JR-078R2L measure 0.122" L x 0.063" W (3.10mm x 1.60mm). ERJ-8RQF8R2V, KTR18EZPF8R20, RMCF1206FT8R20, and RMCF1206JT8R20 measure 0.126" L x 0.063" W (3.20mm x 1.60mm). Height specifications range from 0.025" to 0.028" (0.65mm to 0.70mm). All parts conform to 1206 (3216 Metric) package classification and are compatible with standard 1206 footprints. PCB layout verification is recommended when substituting parts with dimensional variations.

Q: What temperature coefficient differences exist among substitute parts?

A: RMC1/8-8R2JTP specifies -200/+500ppm/°C temperature coefficient. Substitute parts specify ±200ppm/°C (ERJ-8RQF8R2V, RC1206FR-078R2L, RC1206JR-078R2L, RMCF1206FT8R20, RMCF1206JT8R20) or ±100ppm/°C (KTR18EZPF8R20). Temperature coefficient defines resistance change per degree Celsius across the operating temperature range. Applications with strict temperature stability requirements should evaluate temperature coefficient specifications.
